19.Today,we are told,children don't spend enough time in the fresh air.Many of them are addicted to a screen either on a computer or a TV-they seem to be living in a virtual world.They have lost touqh with nature.
But now 400 organizations in the UK,from playgroups to the National Health Service,are encouraging children to have some"wild time".They want kids to swap at least 30 minutes of watching TV or playing computer games for time playing outside.Activities such as building dens,climbing trees,rummaging for conkers and playing hide and seek are just some of the things kids can do.Even if they live in a city,they can go on adventures in the garden or the park.
Children often need a helping hand from mum and dad.They need to be shown what to do and where to go.Andy Simpson from National Health Service says,"We want parents to see what this magical wonder product does for their kids'development,independence and creativity,by giving wild time a go".
    So despite the complicated world that young people grow up in now,it seems that going back to basics and experiencing"nature's playground"is what modern children need.David Bond from Project Wild Thing says,"We need to make more space for wild time in children's daily routine,freeing this generation of kids to have the sort of experiences that many of us took for granted".

5.How is it that siblings (兄弟姐妹) can turn out so differently?One answer is that in fact each sibling grows upin a different family.The firstborn is,for a while,an only child,and therefore has a completely different experience of the parents than those born later.The next child is,for a while,the youngest,until the situation is changed by a new arrival.The mother and father themselves are changing and growing up too.One sibling might live in a stable and close family in the first few years; another might be raised in a family crisis,with a disappointed mother or an angry father.
Sibling competition was identified as an important shaping force as early as in 1918.But more recently,researchers have found many ways in which brothers and sisters are a lasting force in each others'lives.Dr.Annette Henderson says firstborn children pick up vocabulary more quickly than their siblings.The reason for this might be that the later children aren't getting the same one-on-one time with parents.But that doesn't mean that the younger children have problems with language development.Later-borns don't enjoy that much talking time with parents,but instead they harvest lessons from bigger brothers and sisters,learning entire phrases and getting an understanding of social concepts such as the difference between"I"and"me".
A Cambridge University study of 140children found that siblings created a rich world of play that helped them grow socially.Love-hate relationships were common among the children.Even those siblings who fought the most had just as much positive communication as the other sibling pairs.
One way children seek more attention from parents is by making themselves different from their siblings,particularly if they are close in age.Researchers have found that the first two children in a family are typically more different from each other than the second and third.Girls with brothers show their differences to a maximum degree by being more feminine than girls with sisters.A 2003research paper studied adolescents from 185families over two years,finding that those who changed to make themselves different from their siblings were successful in increasing the amount of warmth they gained from their parents.

63.The underlined part"in a different family"(in Para.1)means"A".
A.in a different family environment    B.in a different family tradition
C.in different family crises           D.in different families
64.In terms of language development,later-bornsB.
A.get their parents'individual guidance
B.learn a lot from their elder siblings
C.experience a lot of difficulties
D.pick up words more quickly
65.What was found about fights among siblings?D
A.Siblings hated fighting and loved playing.
B.Siblings in some families fought frequently.
C.Sibling fights led to bad sibling relationships.
D.Siblings learned to get on together from fights.
66.The word"feminine"(in Para.4)means"B".
A.having qualities of parents      B.having qualities of women
C.having defensive qualities       D.having extraordinary qualities.
